Description
本發明是關於接觸型影像感測器單元及使用接觸型影像感測器單元的圖像讀取裝置。尤其是關於搭載柱狀透鏡陣列的長(或短)的接觸型影像感測器單元、及使用接觸型影像感測器單元的圖像讀取裝置。The present invention relates to a contact type image sensor unit and an image reading apparatus using the contact type image sensor unit. In particular, it relates to a long (or short) contact type image sensor unit in which a lenticular lens array is mounted, and an image reading apparatus using a contact type image sensor unit.
以往，是使用影像感測器單元作為傳真機、影印機、掃描器等所利用的圖像讀取裝置。上述的影像感測器單元中，已知有使用柱狀透鏡陣列作為影像感測器單元的接觸型影像感測器單元(CIS；Contact Image Sensor)。該柱狀透鏡陣列構造上由於需要有與讀取寬幅相同長度的柱狀透鏡陣列，所以，設計長尺寸(或短尺寸)的影像感測器時，必須使用適合其讀取寬幅的長度的柱狀透鏡陣列。因此，必須重新準備專用零件，而有變的昂貴的問題。Conventionally, an image sensor unit has been used as an image reading apparatus used by a facsimile machine, a photocopier, a scanner, or the like. Among the image sensor units described above, a contact type image sensor unit (CIS; Contact Image Sensor) using a lenticular lens array as an image sensor unit is known. Since the lenticular lens array is constructed to have a lenticular lens array having the same length as the read wide width, when designing a long-sized (or short-sized) image sensor, it is necessary to use a length suitable for reading the wide width. A lenticular lens array. Therefore, special parts must be re-prepared, and there are problems that become expensive.
因此，例如在專利文獻1提案有：如圖12所示，設計長尺寸的影像感測器時，藉著將一定長的柱狀透鏡陣列30A、30B彼此連接(接合)的方式，使用常用的柱狀透鏡陣列，構成長尺寸的柱狀透鏡陣列30的影像感測器單元。For this reason, for example, as disclosed in Patent Document 1, when a long-sized image sensor is designed, a commonly used lenticular lens array 30A, 30B is connected (joined) to each other. The lenticular lens array constitutes an image sensor unit of the long lenticular lens array 30.
[專利文獻1]日本特開2005-217630號公報[Patent Document 1] Japanese Laid-Open Patent Publication No. 2005-217630
然而，一般柱狀透鏡陣列多半使用適合A4寬幅的者，在上述的接觸型影像感測器單元中，要適合例如A3的寬幅，必須使用連接切斷A4寬幅的柱狀透鏡陣列30A與A4寬幅的柱狀透鏡陣列30B者。此時，柱狀透鏡陣列30的結構上，將柱狀透鏡彼此貼近排列比較好，且必須各別切斷碰觸到連接部的端部，使柱狀透鏡露出。因此，在切斷面會有毛邊發生的問題。又，例如要適合A6寬幅，必須切斷A4寬幅的柱狀透鏡陣列來使用，且在切斷面會有產生毛邊的問題。However, in general, a lenticular lens array is generally used for a wide width of A4. In the above-described contact type image sensor unit, for a wide width such as A3, it is necessary to use a lenticular lens array 30A which cuts off the A4 wide width. With the A4 wide lenticular lens array 30B. At this time, in the structure of the lenticular lens array 30, it is preferable to arrange the lenticular lenses in close proximity to each other, and it is necessary to cut off the end portions that touch the connecting portions and expose the lenticular lenses. Therefore, there is a problem that burrs occur on the cut surface. Further, for example, in order to fit the A6 wide width, it is necessary to cut the A4 wide lenticular lens array and use it, and there is a problem that burrs are generated on the cut surface.
因此，必須進行柱狀透鏡陣列30A/30B的方向管理或削掉毛邊使毛邊不會對柱狀透鏡陣列30的安裝面造成影響，且會有工數增多成本增加問題。Therefore, the direction management of the lenticular lens arrays 30A/30B or the burrs must be removed so that the burrs do not affect the mounting surface of the lenticular lens array 30, and there is a problem that the number of operations increases.

第1柱狀透鏡陣列5A是切斷A4寬幅的柱狀透鏡陣列。第2柱狀透鏡陣列5B也是切斷A4寬幅的柱狀透鏡陣列。藉著連接第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B，可適合A3寬幅。又，第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B的連接面分別被切斷，並以位在第1柱狀透鏡陣列5A的連接部的柱狀透鏡9與位在第2柱狀透鏡陣列5B的連接部的柱狀透鏡9彼此連接的方式貼近排列。柱狀透鏡陣列5是將例如由具有黑色的遮光效果的矽系樹脂接著劑構成的密封劑10填充在接鄰配置的柱狀透鏡9間的間隙，可遮蔽來自外部的光的構造。塗布第1接著劑11覆蓋該密封劑10，連接第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B。The first lenticular lens array 5A is a lenticular lens array in which the A4 wide is cut. The second lenticular lens array 5B is also a lenticular lens array in which the A4 wide is cut. By connecting the first lenticular lens array 5A and the second lenticular lens array 5B, it is suitable for A3 wide. Further, the connection faces of the first lenticular lens array 5A and the second lenticular lens array 5B are cut, and the lenticular lens 9 positioned at the connection portion of the first lenticular lens array 5A is positioned at the second column. The lenticular lenses 9 of the connecting portions of the lens array 5B are closely arranged in such a manner as to be connected to each other. The lenticular lens array 5 is a structure in which a sealant 10 made of, for example, a fluorene-based resin adhesive having a black light-shielding effect is filled in a gap between adjacent lenticular lenses 9 to shield light from the outside. The first adhesive 11 is applied to cover the sealant 10, and the first lenticular lens array 5A and the second lenticular lens array 5B are connected.
然而，第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B切斷時，在寬方向的兩側相對於焦點方向在垂直方向產生0.1mm左右的毛邊12(參閱圖4)。因此，將柱狀透鏡陣列5固定在框8之際，在柱狀透鏡陣列5的安裝面，為了不受到毛邊12的影響，必須進行柱狀透鏡陣列5A及5B的方向管理或避開毛邊12。而圖4所示的20為切斷用的刀具。However, when the first lenticular lens array 5A and the second lenticular lens array 5B are cut, burrs 12 of about 0.1 mm are generated in the vertical direction with respect to the focal direction on both sides in the width direction (see FIG. 4). Therefore, when the lenticular lens array 5 is fixed to the frame 8, the orientation of the lenticular lens arrays 5A and 5B must be managed or avoided from the burrs 12 on the mounting surface of the lenticular lens array 5 so as not to be affected by the burrs 12. . On the other hand, 20 shown in Fig. 4 is a cutting tool.
亦即，框8具備保持柱狀透鏡陣列5的溝狀的保持部13。該保持部13具備：與柱狀透鏡陣列5抵接時抵接的抵接面13A(保持部13單側的壁面)和底面13B。又，在框8，在與底面13B的同一面上設有毛邊餘隙部14。該毛邊餘隙部14是將前述柱狀透鏡陣列5的連接部位置的底面13B的一部分加寬者，且被設在底面13B的短邊方向(寬方向)的兩側。In other words, the frame 8 is provided with a groove-shaped holding portion 13 that holds the lenticular lens array 5. The holding portion 13 includes an abutting surface 13A (a wall surface on one side of the holding portion 13) that abuts against the lenticular lens array 5, and a bottom surface 13B. Further, in the frame 8, a burr portion 14 is provided on the same surface as the bottom surface 13B. The burr portion 14 is a portion of the bottom surface 13B at the position of the connection portion of the lenticular lens array 5, and is provided on both sides in the short-side direction (width direction) of the bottom surface 13B.
而該等的毛邊餘隙部14不僅被設在柱狀透鏡陣列5的連接部位置的地方，被設在柱狀透鏡陣列5的切斷部位置的底面13B的兩壁面側。亦即，為了調整連接後的柱狀透鏡5的長度等，有切斷被連接的柱狀透鏡陣列5的一方的端部或兩方的端部，形成切斷部的情況。這種情況時，由於在該切斷部也會產生毛邊，所以如上述，也可在柱狀透鏡陣列5的切斷部位置的底面13B的兩壁面側設置毛邊餘隙部14。如此而設有將柱狀透鏡陣列5的切斷部及/或連接部位置的底面13B加寬的毛邊餘隙部14。The burr portion 14 is provided not only at the position of the connection portion of the lenticular lens array 5 but also at the wall surface side of the bottom surface 13B at the cutting portion position of the lenticular lens array 5. In other words, in order to adjust the length or the like of the lenticular lens 5 after the connection, one end portion or both end portions of the lenticular lens array 5 to be connected may be cut to form a cut portion. In this case, since the burrs are generated in the cut portion, the burr portion 14 may be provided on both wall sides of the bottom surface 13B of the cut portion position of the lenticular lens array 5 as described above. In this manner, the burr portion 14 that widens the cut portion of the lenticular lens array 5 and/or the bottom surface 13B of the position of the joint portion is provided.
又，在框8設有接著劑流出溝15。接著劑流出溝15是以在被設在框8的保持部13內開口的方式，在抵接面13A間歇性地設置複數個。又，在框8設有連接部退避溝16。連接部退避溝16是位在與柱狀透鏡陣列5的連接部對應的位置，並以在被設在框8的保持部13內開口的方式，被設置在抵接面13A及抵接面13A的對向的壁面。Further, an adhesive outflow groove 15 is provided in the frame 8. The subsequent agent outflow groove 15 is intermittently provided in the abutting surface 13A so as to be opened in the holding portion 13 provided in the frame 8. Further, a connecting portion retreating groove 16 is provided in the frame 8. The connection portion evacuation groove 16 is located at a position corresponding to the connection portion of the lenticular lens array 5, and is provided at the abutting surface 13A and the abutting surface 13A so as to be opened in the holding portion 13 provided in the frame 8. The opposite wall.
藉由該構造，將柱狀透鏡陣列5固定在框8是利用例如未圖示的墊片等，使柱狀透鏡陣列5緊貼在抵接面13A與底面13B。之後，將第2接著劑17分別塗布在連接部退避溝16內，夾著柱狀透鏡陣列5的連接部(密封劑10)的兩旁及在長邊方向，間歇設置的接著劑流出溝15內，將柱狀透鏡陣列5與框8固定在預定的讀取寬幅的全範圍上。(參閱圖5及圖6)With this configuration, the lenticular lens array 5 is fixed to the frame 8, and the lenticular lens array 5 is brought into close contact with the contact surface 13A and the bottom surface 13B by, for example, a spacer (not shown). After that, the second adhesives 17 are respectively applied to the connection portion evacuation grooves 16 so as to sandwich the connection portions (sealant 10) of the lenticular lens array 5 and the adhesive outflow grooves 15 which are intermittently provided in the longitudinal direction. The lenticular lens array 5 and the frame 8 are fixed over the entire range of the predetermined reading width. (See Figures 5 and 6)
此時，將柱狀透鏡陣列5的連接部抵接在底面13B上之際，柱狀透鏡陣列5的連接部可避閉到連接部退避溝16。又，柱狀透鏡陣列5A及5B的切斷時所產生的毛邊12分別可使毛邊12在抵接面13A側的側面退避到毛邊餘隙部14，在抵接面13A對向之側的側面可使毛邊12退避到固定柱狀透鏡陣列5時產生的保持部13的間隙間內及可使毛邊12退避到毛邊餘隙部14。At this time, when the connection portion of the lenticular lens array 5 is brought into contact with the bottom surface 13B, the connection portion of the lenticular lens array 5 can be prevented from being closed to the connection portion evacuation groove 16. Further, the burrs 12 generated when the lenticular lens arrays 5A and 5B are cut may be such that the side surface of the burr 12 on the contact surface 13A side is retracted to the burr portion 14 and the side opposite to the abutting surface 13A. The burrs 12 can be retracted into the gap between the holding portions 13 which are generated when the lenticular lens array 5 is fixed, and the burrs 12 can be retracted to the burr portion 14.
因此，排除毛邊12的影響，將構成柱狀透鏡陣列5的第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B以串聯狀態保持在框8內。Therefore, the influence of the burr 12 is excluded, and the first lenticular lens array 5A and the second lenticular lens array 5B constituting the lenticular lens array 5 are held in the frame 8 in a series state.
本實施形態中，連接柱狀透鏡陣列，做成適合長尺寸的影像感測器的讀取寬幅時，藉由在設在框8的保持部13內設置毛邊餘隙部14可退避柱狀透鏡陣列5的切斷時產生的毛邊12。因此，無須進行連接前後的柱狀透鏡陣列的方向管理或毛邊的削去，可排除毛邊的影響。In the present embodiment, when the lenticular lens array is connected and the reading width is suitable for a long-sized image sensor, the burr portion 14 is provided in the holding portion 13 provided in the frame 8 to retreat from the columnar shape. The burr 12 is generated when the lens array 5 is cut. Therefore, it is not necessary to perform the direction management of the lenticular lens array before and after the connection or the burr removal, and the influence of the burrs can be eliminated.
又，由於第2接著劑17僅塗布在柱狀透鏡陣列5的抵接面13A側，所以因第2接著劑17硬化時的殘渣、滲出等造成的影響僅限於柱狀透鏡陣列5的單側。因此，可排除來自柱狀透鏡陣列5兩側的影響，降低在連接部的柱狀透鏡9間的間隙的發生、偏離、傾斜等的影響。In addition, since the second adhesive 17 is applied only to the contact surface 13A side of the lenticular lens array 5, the influence of residue, bleeding, and the like during curing of the second adhesive 17 is limited to one side of the lenticular lens array 5. . Therefore, the influence from both sides of the lenticular lens array 5 can be eliminated, and the influence of occurrence, deviation, inclination, and the like of the gap between the lenticular lenses 9 of the connection portion can be reduced.
再者，藉著將第2接著劑17塗布在密封劑10的兩側附近，第2接著劑17硬化時的殘渣、滲出等的發生就會以該位置為起點發生，而可使該等的影響退避到柱狀透鏡陣列5的長邊方向的兩端部。因此，可期待對連接部的柱狀透鏡9間的間隙的發生、偏離、傾斜等的影響進一步的降低。Further, by applying the second adhesive 17 to the vicinity of both sides of the sealant 10, the occurrence of residue, bleeding, and the like at the time of curing of the second adhesive 17 starts from the position, and these can be made. The influence is retracted to both end portions of the lenticular lens array 5 in the longitudinal direction. Therefore, it is expected that the influence of the occurrence, the deviation, the inclination, and the like of the gap between the lenticular lenses 9 of the connection portion is further lowered.
又，由於使第1接著劑11的硬度比第2接著劑17的硬度更高，因此可降低因第2接著劑17的溫濕度對第1接著劑11的伸縮等的影響，所以可降低連接部的柱狀透鏡9間的間隙的發生、偏離、傾斜等的影響。In addition, since the hardness of the first adhesive 11 is higher than the hardness of the second adhesive 17, the influence of the temperature and humidity of the second adhesive 17 on the expansion and contraction of the first adhesive 11 can be reduced, so that the connection can be lowered. The influence of the occurrence, deviation, inclination, and the like of the gap between the lenticular lenses 9 in the portion.
接著，針對短尺寸時的柱狀透鏡陣列20與框21的關係進行說明。圖7表示可適用本發明的框21的構造的俯視圖。Next, the relationship between the lenticular lens array 20 and the frame 21 in the case of a short size will be described. Fig. 7 is a plan view showing the configuration of a frame 21 to which the present invention is applicable.
圖7所示的柱狀透鏡陣列20是切斷A4寬幅的柱狀透鏡陣列，為適合A4以下的寬幅者。The lenticular lens array 20 shown in Fig. 7 is a lenticular lens array in which the A4 wide width is cut, and is suitable for a wide range of A4 or less.
框21具備保持柱狀透鏡陣列20的溝狀的保持部13。該保持部13具備有：與柱狀透鏡陣列20抵接時抵接的抵接面13A(保持部13的單側的壁面)和底面13B。又，於保持部13，在與底面13B的同一面上設有毛邊餘隙部14。該毛邊餘隙部14是將前述柱狀透鏡陣列20的長邊方向的最端部的切斷部的位置的底面13B的一部分做寬，且被設在底面13B的短邊方向(寬方向)的兩側。The frame 21 is provided with a groove-shaped holding portion 13 that holds the lenticular lens array 20. The holding portion 13 includes an abutting surface 13A (a wall surface on one side of the holding portion 13) that abuts against the lenticular lens array 20, and a bottom surface 13B. Further, in the holding portion 13, a burr portion 14 is provided on the same surface as the bottom surface 13B. The burr portion 14 is a portion of the bottom surface 13B at the position of the cut portion of the end portion in the longitudinal direction of the lenticular lens array 20, and is provided in the short side direction (wide direction) of the bottom surface 13B. On both sides.
又，在框21設有接著劑流出溝15。接著劑流出溝15是以在被設置在框21的保持部13內開口的方式，在抵接面13A間歇性地設置複數個。Further, an adhesive outflow groove 15 is provided in the frame 21. The subsequent agent outflow groove 15 is intermittently provided in the abutting surface 13A so as to be opened in the holding portion 13 provided in the frame 21.
藉由此構造，將柱狀透鏡陣列20固定在框21是利用例如未圖示的墊片等，使柱狀透鏡陣列20緊貼在抵接面13A與底面13B。之後，在長邊方向將第2接著劑17分別塗布在間歇性設置的接著劑流出溝15內，而將柱狀透鏡陣列20與框21固定在預定的讀取寬幅全面上。With this configuration, the lenticular lens array 20 is fixed to the frame 21, and the lenticular lens array 20 is brought into close contact with the abutting surface 13A and the bottom surface 13B by, for example, a spacer (not shown). Thereafter, the second adhesives 17 are applied to the intermittently disposed adhesive outflow grooves 15 in the longitudinal direction, and the lenticular lens array 20 and the frame 21 are fixed to a predetermined reading width.
此時，柱狀透鏡陣列20的切斷時產生的毛邊12，分別在抵接面13A側的側面，可使毛邊12退避到毛邊餘隙部14，在抵接面13A的對向之側的側面可使毛邊12退避到柱狀透鏡陣列20的固定時形成的保持部13間隙內及毛邊餘隙部14。At this time, the burrs 12 generated at the time of cutting the lenticular lens array 20 are respectively on the side surface on the side of the abutting surface 13A, and the burrs 12 can be retracted to the burr portion 14 on the opposite side of the abutting surface 13A. The side surface can retract the burr 12 into the gap between the holding portion 13 and the burr portion 14 which are formed when the lenticular lens array 20 is fixed.
本實施的形態中，切斷柱狀透鏡陣列，做成適合短尺寸的影像感測器的讀取寬幅時，藉著在被設置在框21的保持部13內設置毛邊餘隙部14，可退避柱狀透鏡陣列20的切斷時產生的毛邊12。因此，無須進行連接前後的柱狀透鏡陣列的方向管理或毛邊的削去，可排除毛邊的影響。In the embodiment of the present invention, when the lenticular lens array is cut and the read width is suitable for a short-sized image sensor, the burr portion 14 is provided in the holding portion 13 provided in the frame 21, The burrs 12 generated when the lenticular lens array 20 is cut off can be retracted. Therefore, it is not necessary to perform the direction management of the lenticular lens array before and after the connection or the burr removal, and the influence of the burrs can be eliminated.
又，由於第2接著劑17僅塗布在柱狀透鏡陣列20的抵接面13A側，所以可使第2接著劑17硬化時的殘渣、滲出等造成的影響僅限於柱狀透鏡陣列20的單側。因此，可排除來自柱狀透鏡陣列20兩側的影響，並可降低柱狀透鏡陣列20往短邊方向(寬方向)的位置偏離、傾斜等的影響。In addition, since the second adhesive 17 is applied only to the contact surface 13A side of the lenticular lens array 20, the influence of residue, bleeding, and the like at the time of curing the second adhesive 17 can be limited to the single lens lens array 20. side. Therefore, the influence from both sides of the lenticular lens array 20 can be eliminated, and the influence of the positional deviation, the inclination, and the like of the lenticular lens array 20 in the short-side direction (wide direction) can be reduced.
[其他的實施的形態][Other forms of implementation]
圖8表示可適用本發明的其他的框8的構造的俯視圖。Fig. 8 is a plan view showing the structure of another frame 8 to which the present invention is applicable.
圖8所示的柱狀透鏡5中，因切斷方法，第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B的切斷時，會有在寬方向的兩側朝焦點方向產生0.1mm左右的毛邊18的情況(參閱圖9)。因此，將柱狀透鏡陣列5固定在框8之際，必須進行柱狀透鏡陣列5A及5B的方向管理或使毛邊18退避，才不會讓毛邊18影響到柱狀透鏡陣列5的安裝面。In the lenticular lens 5 shown in FIG. 8, when the first lenticular lens array 5A and the second lenticular lens array 5B are cut by the cutting method, 0.1 mm is generated in the focus direction on both sides in the width direction. The case of the left and right burrs 18 (see Figure 9). Therefore, when the lenticular lens array 5 is fixed to the frame 8, it is necessary to manage the direction of the lenticular lens arrays 5A and 5B or to retract the burrs 18 so that the burrs 18 do not affect the mounting surface of the lenticular lens array 5.
亦即，框8具備保持柱狀透鏡陣列5的溝狀的保持部13，該保持部13具備有：與柱狀透鏡陣列5抵接時抵接的抵接面13A(保持部13的單側的壁面)和底面13B。又，框8在底面13B設有一對毛邊餘隙溝19。此外，毛邊餘隙溝19並不限於只有一對的情況，可因應毛邊的數量或大小，變更毛邊餘隙溝19的數量或大小。In other words, the frame 8 includes a groove-shaped holding portion 13 that holds the lenticular lens array 5, and the holding portion 13 includes an abutting surface 13A that abuts against the lenticular lens array 5 (one side of the holding portion 13) Wall) and bottom surface 13B. Further, the frame 8 is provided with a pair of burr grooves 19 on the bottom surface 13B. Further, the burr clearance 19 is not limited to a single pair, and the number or size of the burr grooves 19 may be changed in accordance with the number or size of the burrs.
此外，該等的毛邊餘隙溝19不僅被設在柱狀透鏡陣列5的連接部位置的場所，並被設在柱狀透鏡陣列5的切斷部的位置的底面13B。亦即，為了調整連接的柱狀透鏡5的長度等，有切斷連接的柱狀透鏡陣列5的一方的端部或兩方的端部形成切斷部的情況。這種情況，因為在該切斷部也有毛邊產生，所以如上述，也可在柱狀透鏡陣列5的切斷部的位置的底面13B設置毛邊餘隙溝19。如此，在柱狀透鏡陣列5的切斷部及/或連接部的位置的底面13B設有毛邊餘隙溝19。Further, the burr grooves 19 are provided not only at the position of the connection portion of the lenticular lens array 5 but also at the bottom surface 13B of the position of the cut portion of the lenticular lens array 5. In other words, in order to adjust the length of the lenticular lens 5 to be connected or the like, one end portion or both end portions of the lenticular lens array 5 that are connected to each other may be formed as a cut portion. In this case, since the burr is also generated in the cut portion, the burr groove 19 may be provided on the bottom surface 13B of the position of the cut portion of the lenticular lens array 5 as described above. In this manner, the burr groove 19 is provided in the bottom surface 13B of the cut portion of the lenticular lens array 5 and/or the position of the joint portion.
又，在框8設有接著劑流出溝15。接著劑流出溝15是以在被設置在框8的保持部13內開口的方式，在抵接面13A間歇性地設置複數個。又，在框8設有連接部退避溝16。連接部退避溝16是位在與柱狀透鏡陣列5的連接部對應的位置，並以在被設置在框8的保持部13內開口的方式，設置在抵接面13A、及抵接面13A的對向的壁面。Further, an adhesive outflow groove 15 is provided in the frame 8. The subsequent agent outflow groove 15 is intermittently provided in the abutting surface 13A so as to be opened in the holding portion 13 provided in the frame 8. Further, a connecting portion retreating groove 16 is provided in the frame 8. The connection portion evacuation groove 16 is located at a position corresponding to the connection portion of the lenticular lens array 5, and is provided at the abutting surface 13A and the abutting surface 13A so as to be opened in the holding portion 13 provided in the frame 8. The opposite wall.
藉由該構造，將柱狀透鏡陣列5固定在框8是利用例如未圖示的墊片等，使柱狀透鏡陣列5緊貼在抵接面13A與底面13B。之後，在連接部退避溝16內，將第2接著劑17分別塗布在夾著柱狀透鏡陣列5的連接部(密封劑10)兩旁及在長邊方向，分別塗布在間歇性設置的接著劑流出溝15內，而將柱狀透鏡陣列5與框8固定在預定的讀取寬幅的全面上(也參閱圖10)。With this configuration, the lenticular lens array 5 is fixed to the frame 8, and the lenticular lens array 5 is brought into close contact with the contact surface 13A and the bottom surface 13B by, for example, a spacer (not shown). Thereafter, in the connection portion evacuation groove 16, the second adhesive 17 is applied to both sides of the connection portion (sealant 10) sandwiching the lenticular lens array 5 and in the longitudinal direction, and is applied to the intermittently disposed adhesive. Out of the groove 15, the lenticular lens array 5 and the frame 8 are fixed to a predetermined reading width (see also Fig. 10).
此時，將柱狀透鏡陣列5的連接部抵接在底面13B上之際，柱狀透鏡陣列5的連接部可退避到連接部退避溝16。又，柱狀透鏡陣列5A及5B切斷時產生的毛邊18可退避到毛邊餘隙溝19。At this time, when the connection portion of the lenticular lens array 5 is brought into contact with the bottom surface 13B, the connection portion of the lenticular lens array 5 can be retracted to the connection portion evacuation groove 16. Further, the burrs 18 generated when the lenticular lens arrays 5A and 5B are cut can be retracted to the burr clearance grooves 19.
因此，可排除毛邊18的影響，可將構成柱狀透鏡陣列5的第1柱狀透鏡陣列5A與第2柱狀透鏡陣列5B以串聯狀態保持在框8內。Therefore, the influence of the burrs 18 can be eliminated, and the first lenticular lens array 5A and the second lenticular lens array 5B constituting the lenticular lens array 5 can be held in the frame 8 in a series state.
本實施的形態中，連接柱狀透鏡陣列，做成適合長尺寸的影像感測器的讀取寬幅時，藉由在被設置在框8的保持部13內設置一對毛邊餘隙溝19，可退避柱狀透鏡陣列5的切斷時產生的毛邊18。因此，無須進行連接前後的柱狀透鏡陣列的方向管理或毛邊的削去，可排除毛邊的影響。In the embodiment of the present invention, when the lenticular lens array is connected to a reading width suitable for a long-sized image sensor, a pair of burr grooves 19 are provided in the holding portion 13 provided in the frame 8. The burrs 18 generated when the lenticular lens array 5 is cut can be retracted. Therefore, it is not necessary to perform the direction management of the lenticular lens array before and after the connection or the burr removal, and the influence of the burrs can be eliminated.
又，由於第2接著劑17僅被塗布在柱狀透鏡陣列5的抵接面13A側，可使第2接著劑17硬化時的殘渣、滲出等造成的影響僅限於柱狀透鏡陣列5的單側。因此，可排除來自柱狀透鏡陣列5兩側的影響，並可降低往連接部的柱狀透鏡9間的間隙的產生、偏移、傾斜等的影響。In addition, since the second adhesive 17 is applied only to the contact surface 13A side of the lenticular lens array 5, the influence of residue, bleeding, and the like when the second adhesive 17 is cured can be limited to the single lens lens array 5. side. Therefore, the influence from both sides of the lenticular lens array 5 can be eliminated, and the influence of generation, offset, inclination, and the like of the gap between the lenticular lenses 9 of the connection portion can be reduced.
再者，藉由將第2接著劑17塗布在密封劑10的兩側附近，使第2接著劑17硬化時的殘渣、滲出等的產生成為會以該位置為起點產生，且可使該等的影響退避到柱狀透鏡陣列5的長邊方向的兩端部。因此，可期待進一步降低對連接部的柱狀透鏡9間的間隙的產生、偏離、傾斜等的影響。In addition, when the second adhesive 17 is applied to the vicinity of both sides of the sealant 10, the occurrence of residue, bleeding, and the like when the second adhesive 17 is cured is generated from the position, and these can be generated. The influence is retracted to both end portions of the lenticular lens array 5 in the longitudinal direction. Therefore, it is expected to further reduce the influence of the occurrence, the deviation, the inclination, and the like of the gap between the lenticular lenses 9 of the connection portion.
又，由於使第1接著劑11的硬度比第2接著劑17的硬度更高，因此可降低因第2接著劑17的溫濕度對第1接著劑11的伸縮等的影響，所以可降低連接部的柱狀透鏡9間的間隙的發生、偏離、傾斜等的影響。In addition, since the hardness of the first adhesive 11 is higher than the hardness of the second adhesive 17, the influence of the temperature and humidity of the second adhesive 17 on the expansion and contraction of the first adhesive 11 can be reduced, so that the connection can be lowered. The influence of the occurrence, deviation, inclination, and the like of the gap between the lenticular lenses 9 in the portion.
接著，針對短尺寸時的柱狀透鏡陣列20與框21的關係進行說明。圖11表示可適用本發明的框21的構造的俯視圖。Next, the relationship between the lenticular lens array 20 and the frame 21 in the case of a short size will be described. Fig. 11 is a plan view showing the configuration of a frame 21 to which the present invention is applicable.
圖11所示的柱狀透鏡陣列20是切斷A4寬幅的柱狀透鏡陣列，為適合A4以下的寬幅者。The lenticular lens array 20 shown in Fig. 11 is a lenticular lens array in which the A4 width is cut, and is suitable for a wide range of A4 or less.
框21具備保持柱狀透鏡陣列20的溝狀的保持部13。該保持部13具備有：與柱狀透鏡陣列20抵接時抵接的抵接面13A(保持部13的單側的壁面)和底面13B。又，於保持部13，在底面13B設有毛邊餘隙溝19。該毛邊餘隙溝19是被設在前述柱狀透鏡陣列20的最端部的切斷部的位置的底面13B。而且，毛邊餘隙溝19並不限於一對的情況，可因應毛邊的數量或大小，變更毛邊餘隙溝19的數量或大小。The frame 21 is provided with a groove-shaped holding portion 13 that holds the lenticular lens array 20. The holding portion 13 includes an abutting surface 13A (a wall surface on one side of the holding portion 13) that abuts against the lenticular lens array 20, and a bottom surface 13B. Further, in the holding portion 13, a burr groove 19 is provided on the bottom surface 13B. The burr groove 19 is a bottom surface 13B provided at a position of a cutting portion at the most end portion of the lenticular lens array 20. Further, the burr clearance 19 is not limited to a pair, and the number or size of the burr grooves 19 may be changed in accordance with the number or size of the burrs.
又，在框21設有接著劑流出溝15。接著劑流出溝15是以在被設置在框21的保持部13內開口的方式，在抵接面13A間歇性地設置複數個。Further, an adhesive outflow groove 15 is provided in the frame 21. The subsequent agent outflow groove 15 is intermittently provided in the abutting surface 13A so as to be opened in the holding portion 13 provided in the frame 21.
藉由此構成，將柱狀透鏡陣列20固定在框21是利用例如未圖示的墊片等，使柱狀透鏡陣列20緊貼在抵接面13A與底面13B。之後，在長邊方向將第2接著劑17分別塗布在間歇性設置的接著劑流出溝15內，而將柱狀透鏡陣列20與框21固定在預定的讀取寬幅全面上。With this configuration, the lenticular lens array 20 is fixed to the frame 21, and the lenticular lens array 20 is brought into close contact with the contact surface 13A and the bottom surface 13B by, for example, a spacer (not shown). Thereafter, the second adhesives 17 are applied to the intermittently disposed adhesive outflow grooves 15 in the longitudinal direction, and the lenticular lens array 20 and the frame 21 are fixed to a predetermined reading width.
此時，柱狀透鏡陣列20切斷時在切斷面的兩側產生的毛邊18可退避到毛邊餘隙溝19。At this time, the burrs 18 generated on both sides of the cut surface when the lenticular lens array 20 is cut can be retracted to the burr groove 19.
本實施的形態中，切斷柱狀透鏡陣列，做成適合短尺寸的影像感測器的讀取寬幅時，藉由在被設置在框21的保持部13內設置一對毛邊餘隙溝19的方式，可退避柱狀透鏡陣列20的切斷時時產生的毛邊18。因此，無須進行連接前後的柱狀透鏡陣列的方向管理或毛邊的削去，可排除毛邊的影響。In the embodiment of the present invention, when the lenticular lens array is cut and the reading width is suitable for a short-sized image sensor, a pair of burr grooves are provided in the holding portion 13 provided in the frame 21. In the manner of 19, the burrs 18 generated when the lenticular lens array 20 is cut off can be retracted. Therefore, it is not necessary to perform the direction management of the lenticular lens array before and after the connection or the burr removal, and the influence of the burrs can be eliminated.
又，由於第2接著劑17僅被塗布在柱狀透鏡陣列20的抵接面13A側，可使第2接著劑17硬化時的殘渣、滲出等造成的影響僅限於柱狀透鏡陣列20的單側。因此，可排除來自柱狀透鏡陣列20兩側的影響，並可降低柱狀透鏡陣列20往短邊方向(寬方向)的位置偏離、傾斜等的影響。In addition, since the second adhesive 17 is applied only to the contact surface 13A side of the lenticular lens array 20, the influence of residue, bleeding, and the like when the second adhesive 17 is cured can be limited to the single lens lens array 20 side. Therefore, the influence from both sides of the lenticular lens array 20 can be eliminated, and the influence of the positional deviation, the inclination, and the like of the lenticular lens array 20 in the short-side direction (wide direction) can be reduced.
此外，使用在柱狀透鏡陣列5的柱狀透鏡陣列不限於A4寬幅，且，因應需要可連接任意根。又，在柱狀透鏡陣列5也可連接部及切斷部混合在一起。Further, the lenticular lens array used in the lenticular lens array 5 is not limited to the A4 wide width, and any root may be connected as needed. Further, the lenticular lens array 5 is also provided with a connectable portion and a cut portion.
